IMPROVED WRINGING-MACHINE.

Specification forming part oi` Leiters Patent No. 37,007, dated h'ovnnzber 25, liz-(2.

To all whom i may concern:

Beitknown that I, WILLIAM B. RHoADs, of South Dedham, in the State of Massachusetts, have invented a new and useful Improvement in Vringing-Machines and Pressure Devices Therefor; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accornpanying drawings,formin g part of this specifiliation, in which-- Figure l is a front elevation of a wringingmachine with my improvements. Fig. 2 is a vertical transverse section of the same. Fig. 8 is a longitudinal section through one of the standards of the frame. Fig. tis a side view. Fig. 5 is a modification of the clamp. Fig. 6 is a modification of the pressure devices. Fig. 7 is an end view of the cross-tie B of the machine shoWn in Fig. 1.

Similar letters of reference in the several figures indicate corresponding parts.

The frame of my wringing-machine consists of two strong uprights, A A, and a strong beveled cross-tie, B. The uprights are furnished with back stops, c a, and are grooved on their inner sides, as at b b. The cross-tie is beveled down from its front top edge to near its rear bottom edge, so as to freely shed and conduct the Water back into the tub to which the wringer is attached. It also has rectangular tenons on its ends, as indicated atco, and it is further grooved on its bottom, as indicated at d. The three parts thus constructed are tied together by means of a screw clamp-rod, C, the clamprod passing through the uprights A A and along in the groove d of the cross-tie, and acts, by reason of its head and a clamp-nut, c, on its screw-threaded end f, to bring the parts together, so that the tenons of the cross-piece iit snugly into the grooves or mortises b of the uprights. This construction gives great rmness and strength, and aii'ords every facility for separating the frame for packing purposes. It also is so simple that any person can set the machine up. Vithin this frame rubber rollers D D are arranged, one above the other, just above the cross-tie B. Thelower roller, D, is fixed as to sliding motion, but is capable of revolving. The metal shaft of this roller is long enough to constitute an arm for a handcrank, E, as shown. The upper roller, D', has

frame A A as well as in its rubber portion, v

I arrange long still springs, which constitute levers of the first order, over the roller and so as to bear down upon the short pillarsg g, and through them upon the journals of the roller D, as represented in Figs. l, 2, 8 of the drawings. These lever-springs F F are hinged, respectively, at one of their ends to the frame A, as indicated at i j, and are held at a tension or in a distended condition by means of ratchetstops formed on plates G G', which are screwed to the outer sides of the uprights A A, as represented. It will be noticed by the drawings thatone spring-lever is hinged to one upright and the other to another upright, and that the spring-lever F acts upon one of the journals of the roller D', while the leverspring F acts on the other journal of said .roller. It will also be noticed that the series of notches on the plates G G admit of the power of the lever-spring being regulated laccordingly as circumstances may require. The springs are represented in Fig. l as curved at their ends, so as to accommodate themselves to the location and form of the stops 5 but this is not essentially necessary, as the lever-springs may be nearly straight from a point near where they hinge to the framepandlhavea wire loop, H, attached to their loose end, as indicated in Fig. 6. In this case holding-pins k k may be substituted for the notched plates; or the notched plates themselves may be used, the loops taking hold under the notches.1 In this connection l would remark that my invention under this head consists in the lever-springs for use on wringing-machines for producing pressure on the roller which slides in its bearings, and is not conned to any particular details for attaching them so long as the mode of attachment enables them to perform the function of a lever and spring combined.

As a convenient and effective means of attaching the wringing-machine to a tub or other article, I have devised a casting, Iy; of the construction shown, and in connection with such casting provided a retaining-nut, S, and a headed screw, J, with a shoulder or collar, Z, below its head, for coupling it to the casting, a vertical slot, 2, in the casting admitting the screw to its proper position. The casting has three prongs, 'm m m', one of which, m', having a scroll-bend or oblique twist in it below the side prongs, m m, so as to conform to the curve of the tub, and to come in proper clamping relation to it when the wringer is applied centrally along the top edge of the tub. The casting'with the screw and nut, in order to be used, requires that the front portions of the lower ends of the wringerstandard should be cut away after the manner of a beveled scroll, as indicated at p p; also thata round passage, q, and a square one, q', at right angles to and intersecting oneanother, should be cut through the standards,and,further, that open side notches, rr, be cut in the inner and outer sides of the standards, all substantially as represented. In the application ofthe clamp to the wringer the nutS enters the passage q',

and its eye stands concentric with the passage q, and through the passage g and the nut the screw J extends, while the side prongs, mm, of the casting lit into the open mortises, so as to confine the nut. By turning the screw J in the nut S the prong mis caused to move in or outward from the tub and to bind or cease to bind thereon, accordingly as the screw is moved. The vertical prong m may be semicircular in form, as shown in Fig. l. In this construction it is bent so as to stand under the body of the standard and so as to strongly clasp and adjust itself to the flaring edge of the tub in substantially the same manner as shown in the other figures.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. Lever-springs, as means for producing pressure on and allowing yield ofthe moving roller of wringing-machines, substantially as set forth.

2. rlhe three-pronged device m 'm m', with the shouldered screw J, nut S. and wringingmachinestandards A A, substantially as and for the purpose set forth.

W'itness my hand and seal in the matter of my application for a patent for a wringingmachine, this 24th day of April, A. D. 1862.
